Abstract
The utility model relates to a composite diaphragm of a loudspeaker. The loudspeaker comprises a magnetic circuit system, a vibration system and a loudspeaker bracket. The magnetic circuit system comprises magnetic steel, a pole piece and a magnetic shield. The vibration system comprises a voice coil and a diaphragm, wherein the voice coil is fixed on the diaphragm. The utility model is characterized in that the composite diaphragm is a composite diaphragm. The middle part of the composite diaphragm is made of polyarylate (PAR) material and the peripheral part of the diaphragm around the PAR material is made of polyetheretherketone . Due to the adoption of the above structure, the bass response of the loudspeaker and the medium-high-frequency tone quality of the loudspeaker are well balanced, so that both the low-frequency sound and the high-frequency sound of the loudspeaker are ensured to be good in sound quality and volume.
Description
Technical field
The utility model relates to the vibrating diaphragm of a kind of loud speaker, particularly a kind of loud speaker.
Background technology
The vibrational system of loud speaker is heavier, and the bass effect of loud speaker can be relatively good, if but the heavier meeting of vibrational system causes loudspeaker sensitivity to reduce, thus so that sound diminishes, can't guarantee the tonequality of loudspeaker medium high frequency frequency.
Summary of the invention
The utility model technical issues that need to address provide all good diaphragms of loudspeaker of a kind of low frequency and medium-high frequency acoustical quality.
For solving above-mentioned technical problem, the composite type diaphragm of the utility model loud speaker, described loud speaker comprises magnetic circuit system, vibrational system and loudspeaker support, described magnetic circuit system comprises magnet steel, pole piece and magnetic cover, described vibrational system comprises voice coil loudspeaker voice coil and vibrating diaphragm, described voice coil loudspeaker voice coil is fixed on the vibrating diaphragm, and described vibrating diaphragm is composite type diaphragm, and described composite type diaphragm centre is for PAR material vibrating diaphragm and be arranged on PAR material vibrating diaphragm PEEK material vibrating diaphragm all around.
Further, be provided with the ring that increases its toughness on the PEEK material vibrating diaphragm in composite type diaphragm bight.
After adopting said structure, well balance loud speaker bass effect and medium-high frequency tonequality, guaranteed that loud speaker low frequency and high frequency all have good tonequality and volume effect.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic cross-section of the utility model ring.
Among the figure: 1 is PAR material vibrating diaphragm, and 2 is PEEK material vibrating diaphragm, and 3 is ring
Embodiment
The composite type diaphragm of loud speaker as shown in Figure 1, described loud speaker comprises magnetic circuit system, vibrational system and loudspeaker support, described magnetic circuit system comprises magnet steel, pole piece and magnetic cover, and it is inner that magnet steel is fixed on the magnetic cover, and pole piece is fixed on and is used for the magnetic field that stable and concentrated magnet steel forms on the magnet steel.Described vibrational system comprises voice coil loudspeaker voice coil and vibrating diaphragm, and described vibrating diaphragm is fixed on the voice coil loudspeaker voice coil, and voice coil loudspeaker voice coil is inserted in the magnetic gap of magnetic circuit system.Adopt electrical conductor to make voice coil loudspeaker voice coil, voice coil loudspeaker voice coil is equivalent to a current－carrying conductor when inputting a tone currents signal in the voice coil loudspeaker voice coil.In magnetic field, voice coil loudspeaker voice coil can be subject to an active force makes voice coil loudspeaker voice coil produce vibration, thereby drives the vibrating diaphragm vibration, sounds.
In the middle of the described composite type diaphragm for high-performance PAR material vibrating diaphragm 1 and be arranged on light weight and high tenacity PEEK material vibrating diaphragm 2 around the PAR material vibrating diaphragm, described composite type diaphragm be shaped as rectangle, adapt with contoured cradle.Adopt the high-toughness material of light weight because of outstanding limit around the composite type diaphragm, guaranteed the loud speaker low-frequency effect, so that bass is abundant.Simultaneously, the middle high performance material that adopts has guaranteed loudspeaker medium high frequency frequency tonequality.So the good balance of composite type diaphragm structure the tonequality of loud speaker bass effect and medium-high frequency, improved speaker volume.
As depicted in figs. 1 and 2, in order further to increase toughness and the rigidity of lightweight PEEK material vibrating diaphragm 2, the PEEK material vibrating diaphragm in described composite type diaphragm bight is provided with ring 3.Described ring 3 is to form fold on PEEK material vibrating diaphragm surface, and described fold forms a plurality of ellipticity rings, and described ellipticity ring is arranged on the bight of composite type diaphragm.Described ring 3 is provided with corresponding shape at the vibrating diaphragm mould, forms in the lump when vibrating diaphragm is shaped.
Claims (2)
